I am aware that automatic grouping is not recommended for Adobe Acrobat (/other Adobe PDF apps) and only have explorer set to auto group. But whenever I open any PDF, Groupy is creating a tab for it in a pre-existing group. The tab doesn't work--only one PDF that is currently open (the first to be opened) actually appears, and all others do not. I didn't have this problem originally; all PDFs worked without problem. I am also using Fancy Zones (PowerToys) to snap apps to grids, but disabling that does not solve anything. If I click and draf the PDF tab to remove from group, it remains invisible. The only option is to close all PDFs and open the one I want to see. As you can imagine, everything has come to a halt due to this.
